For providers of composite services, preventing cases of SLA violations is crucial. Previous
work has established runtime adaptation of compositions as a promising tool to achieve SLA …

Due to distribution, participant autonomy and lack of local control, service-based systems
operate in highly dynamic and uncertain environments. In the face of such dynamism and …

Abstract Service compositions put together loosely-coupled component services to perform
more complex, higher level, or cross-organizational tasks in a platform-independent manner …

As service-oriented systems are increasingly composed of third-party services accessible
over the Internet, self-adaptation capabilities promise to make these systems become robust …

At present, the constant development of information and communication technologies (ICTs)
is allowing the creation of applications and services that require the automated and …

Furnishing service-oriented systems with self-adaptation capabilities allows those systems
to become resilient against failures of their constituent services. Especially proactive …

Abstract Service-based Applications (SBAs) will increasingly be deployed in highly
distributed and dynamic settings. To a large extent this dynamicity is caused by the trend to …

Software as a Service reflects a 'service‐oriented'approach to software development that is
based on the notion of composing applications by discovering and invoking network …

Service Oriented Computing enables distributed applications that orchestrate existing
services exported by remote providers. This paradigm requires to explicitly handle possible …

We study QoS-aware management of service orchestrations, specifically for orchestrations
having a data-dependent workflow. Our study supports multi-dimensional QoS. To capture …
